I seem to be getting a shitty signal where are all u guys getting your tach signal from plz any help would be great
Striped wire on your coil. I believe one is purple and the other is a whitefish color with a stripe on it. That's where I picked up my tach reading for my window switch

I'm pretty sure it doesn't matter which coil you choose. I hooked mine up to the uncommon colored wire on the 2nd to last coil on the drivers side. Also, make sure you set the box to 1 cylinder when setting it up initially. And one other thing, when you set your RPM points and cylinder style, it will remember the settings. This way you don't have to reset them every time you run it.
Some others on here have said the coil signal is dirty and they have switched to using an injector wire. But others swear by the coil wire. Maybe some of the more knowledgeable guys will chime in on the subject. And FWIW, American Muscle used to have a pdf file showing how one user installed the MSD 8969, but it's no longer on their site. Those instructions state the user tapped into the non common colored wire on the fuel injector harness. I'm pretty sure either method will work.
Hope this helps.

I am having the same issue with mine. Recently found out the solenoid is only getting 10v with the msd window switch hooked up and when the msd is taken out of the equation, the solenoid sees the full 12v it wants/needs. I contacted BBR and without batting an eye, he said he would get me a new msd box sent out, I just need to send the bad one in first.
Mine goes to the negative side of the #8 injector(one with stripe). Could try that but with 10v coming out of the window switch I'm thinking send it back.
Look I made this a #8 thread. Never mind no one uses the search function anymore.
Stole this from another thread in "power adder" section. . Laugh at my funny because you didn't search. j/K have no cows.
Yes sir. You get yours working? With 10v out it almost has to be a bad switch.
Runs good with the msd bypassed for now, I'll confirm that on Friday at the track.
OP, Is the spray cutting in and out when you make a hit? try bypassing the msd and see what it does. FYI, apparently the msd window switches are known to be complete garbage. The nitrous package I bought from BBR now includes a NX window switch instead of the msd
